The present invention relates to the field of communications and discloses a method, device, and system for withdrawing routes. When routes are withdrawn, by carrying route withdrawal related information in a route update message and withdrawing routes according to the route withdrawal related information, a Border Gateway Protocol (BGP) path detection procedure is avoided and the time of network topology convergence is shortened. Further, by carrying identifiers information of routes to be withdrawn in the update message, specific routes can be withdrawn in a scenario where there are multiple BGP routes; by carrying characteristic information of routes to be withdrawn in batches in the update message, a group of routes with the common characteristic can be withdrawn in batches; and by carrying route withdrawal policy information in the update message, the collaboration between BGP peers may be optimized, and the quality and performance of the network may be improved. |
